IQDJED JOURNAL-BOX LID AND METHOD 0F MAKING SAME.

To all whom t may concern:

Be it known that I, VCLAUS J. WERNER CLssnN, a citizen of the United States of America, residing in Davenport, Iowa, am. the inventor of certain new and useful Improveniente in Hooded Journa1-Box Lids and Methods of Making Same, ofwhich the following is a true, complete, and concise description.

My invention relates to lids for journal boxes and the like. It also relates tomethods l of making such articles. One of the objects of my invention 'is to provide a hooded pressed steel journal box lid which shall substantially prevent the accumulation of dirt in the box which occurs with the present type of hooded lid.

Among other objects of my invention are:

' to provide a journal box lid of the hooded 20Y type which shall be capable of ready and economical manufacture and which shall be not only rugged whenin use, but readily repaired when deformed;l and to provide a hooded journal box lid comprising a minimum number of parts.

' The hooded ty e of journal box lid has certain recognize advantages as compared with the non-hooded type. I have found, however, that thepressed hoods of lids prior to my invention, permit a circulation of ai-r from outside the box into the interior of the same.

, As journal boxes are used in an-extremely dusty lace, this circulation of air carries much ust into the interior of the boxes and the dust is caught by the oil in the box and .retained thereln, thus increasing the Wear on the journals and bearin brasses. 'According to myinvention, this circulation of air 1s prevented by making the body of the lid to cover the box closely over the entire top of the box when closed and forming the hood on a part lying above the body of the lid. In manufacturing a lid according to mypinvention, I first make a blank by pressing or stampingfro'm metal sheet or plate,` said blank having a body of the same outline as the box and adapted when closed to cover the box closely at all points thus preventing any circulation of au' over the edge of the box when the lid-'is in use. Integral with the part of the blank designed to act as the body or lid proper is a portion designed' to form the h ood vand the hinge eyes. The blank is then bent back on itself lid according to hood, 7, is high parts of the blank ever, will best be understood from the following ,description taken ,with the accompanying drawings in which: A

Fig. 1 is the plan view of a journal box my invention. Fig. 2 is -a section on the line 2 2 of Fig. 1. f l

Fig. 3' is a view taken from the front of F 1g. 1', parts being shown Vin elevation and parts in section on the line `3 3 of Fig. 1.

Fig. 4 is a plan view ofa blank used in making a journal box lid according to m invention and illustrating the blank as 1t appears at an intermediate point in the process of manufacturing the lid.

Fig. 5 is a section on the line 5-5 of Fig. 4. Y

v Referring in detail to the drawing, 1 indicates the body of the lid which ispreferably made of sheet steel or the like. A downturned flangev 2 surrounds body 1 on three sides. AThis flange serves to stiifen the lid and also to hold itin place when in use. The front edgel of lidV 1 is formed with a finger piece 3a. The body 1 has a symmetrical U- shaped depression 3 therein for imparting rigidity to the lid.- The Vnon-depressed portion 4 which projects within the U-shaped depression serves as the support of the orward end of the spring` 5. The rivet 5 secures the front end of spring 5 to fiat art 4. l P Integral with the body 1 along the rear edge of the body-are two eyes 6, 6. A hood 7 extends along the inner edges of the eyes, but is disconnected from body 1 except for the connection through they eyes 6. This at its rear end as most clear] appears in Fig. 2, but slopes )downwardly from rear to front and also contracts laterally from rear .to front.

From

hood 7 it results thatthe hood is brought down to a shallow channel "lu atitslfront partit Y The vchannel 7* just ts the spring 5 at a point slightly to the rear of rivet 5a.v

A forms a ulcrum `for the spring.

In forming a lid or cover according to my invention, the blank 1A (Figs. 4 and 5) is pressed or stamped from a suitable sheet or plate and-pressed to provide a bodyV 1 having the features previously described. Along vits rearedge, blank 1A is bent downwardly forming a flange 9.- Flange 9, however, inclines outwardly and rearwardly from the body 1 and does not extend downwardly as far as lange 2. Immediately to the rear 'of inclined flange 9, blank 1A is cut away as illustrated at 10, Fig. 4, for a space extending somewhat on each side of the centre line -of the blank. On each side ofspace 10, however, the blank 1A comprises strips 11 which are integral with and extend rearwardly from flange 9. Each of strips 11 comprises a dat portion 12, next the flange 9. Portions 12 are iiat and parallel to body 1. At the rear edge' of each flat wardly orming an inclined portion 13. Following inclined portion 13 in each strip is a second'iat portion 14 parallel to ,part 12 and which connects in turn with a downwardly and outwardly inclined part 15. Part 15 connects in turn with half round part 16, which curves around so that its rear part is directed toward the plane of body 1. Half round section 16 is followed in the rearwarddirection by iiat part 17. Owing to the circular arc covered by the portion 16, flat parts 17 in the blank lie in a plane at an angle of about 45 degrees to the plane of body 1. Flat part 17 connects with a curved portion 18 and curved part 18 connects in turn with one of the fiat wings 8, previously mentioned. It is apparent from Fig. 5 that hood 7 and channel 7a unite each pair of parts 16, 17, 18 and 8. Moreover, the concavity of the hood is on the opposite face or side of the blank from that of the body portion. These parts having been pressed into the shapes illustrated in Fig. 5, are held rigidly in the relative positions shown by the stifening action of hood 7. Moreover, each pair of parts 12 and 13 are stifened by a iiute 12a extendy ing from thev rear edge of flange 9 to the front end of the corresponding dat part 14. It is apparent that only the flat parts 14 are unstiffened of all the parts between the flange 9 and the channel 7".

In manufacturing a lid according to my yby rivets 8a, 8"L

ortion 12 the strip is bent downa v mesma toward the body portion and a chamber is formed toA receive the spring 5. The flat part 14 being unstiened is readily bent into a half round form, parts 14, 14 and 15, 15 of the blank combining to form the hinge eyes 6, 6 of the finished lid or cover.

The hood 7 and connected parts being in the position shown in Figs. 1, 2, and 3, the spring 5 is put in place as illustrated and riveted to the body 1 of the lid by rivet 5". The wings 8, 8 are then riveted to body 1 While I have illustrated the parts 5 and 8, 8 as fastened to the body 1 by means of rivets, I do not limit myself to this, as other means, as for example, spot welding, maybe employed.

It will be geen una the outline of the body is not cut away beneath the hood 7, but that the flange 9 to which the hinge eyes are attached runs straight across between adjacent corners' of the lid and is adapted to close the journal box on which the lid is used so as to prevent circulation of air over the rear edge of the box when the lid is closed.

It will be seen that I have provided a' lid for use on journal boxes 4or the like which may be readily manufactured and whichA is rugged in use, but which has a minimum of parts and is readily repaired if deformed. It will be seen also that a lid according to my invention not only has the advantages mentioned together with those of the usual hooded type, but comprises a hood and a body acting when in closed position to prevent circulation of air over the edge of the box.

Having thus described my invention, I l

claim:

`1. A journal box lid comprising integral body, hinge eyes and hood, all of metal plate, said body underlying said hood as far as the line of the box cooperating with the lidwhereby dust is substantially excluded from the journal box when the lid is closed over the same.

2. The method of making a hooded journal box lid comprising pressing out of a single metal plate, a concave body portion and a concave hood portion connected by spaced strips only, the concavities of said portions being pressed in opposite sides of the blank and bending said hood portion over on said body portion and making said strips into hinge eyes.

3. The method of makinga hooded journal box lid comprising pressing out of a single metal plate a body portion and a con- Cave hood portion spaced apart but connectmesme' 4, The method of mah'ng a. hooded journal box lid comprising pressing out of a single metal plate e bodyr portion having a substantially square outline and a concave hood p ortion connected by strip material only bending said hood portion over on seid body portion with the concavity in the hood facing the body portion of the lid and forming the lst part of said strip material into a. hollow cylinder. l Y,
